What this example teaches
Error Handling
Output
The script reads or transforms sales rows and status values and prints a result you can verify.
Line-by-line explanation
- Line 1 sets up the Error Handling example: items = ["Error Handling", "practice", "review"].
- Line 2 adds one required part of the working pattern: for position, item in enumerate(items, start=1):.
- Line 3 exposes the output so you can verify the behavior: print(f"{position}. {item}").
Why this example is useful
This example is useful because it isolates error handling without surrounding noise, so you can see the idea clearly.
Where it is used in real projects
Error Handling appears in real Python work when a feature needs a clear pattern that can be reviewed and changed safely.
